WebApr 9, 2024 · Poly-ether-ether-ketone (PEEK) is commonly employed in dental prostheses owing to its excellent mechanical properties; however, it is limited by its low bond strength with dental resin cement. This study aimed to clarify the type of resin cement most suitable for bonding to PEEK: methyl methacrylate (MMA)-based resin cement or composite … WebThe high molecular weight (M n = 5.93 × 10 5 Da) PMMA can be synthesized at 10 kbar, but a relatively low monomer conversion (46%) and high molecular weight distribution (PDI = 1.96) are obtained. The polymerization rate and molecular weight can both be increased at 6 kbar, giving a well-defined PMMA with a M n of 1.88 × 10 6 Da.
WebApr 12, 2024 · As shown in Table 1, sodium ascorbate seems to give the highest polymerization rate under the designed polymerization conditions.The monomer conversion reached about 48% in 6 h, providing a PMMA with molecular weight of 9800 and Đ = M w /M n = 1.43. This main reason may be attributed to the fact that sodium ascorbate changed … http://publications.iowa.gov/22012/
